There is “pretty compelling” evidence that the Government’s listening post, the UK Government Communications Headquarters (GCHQ) is passing information to the US to help it locate targets for drone attacks in Pakistan’s tribal areas, believed to be a terror hub of the Haqqani network and the Taliban, it has been claimed.

Former director of public prosecutions, Lord Macdonald, said the British people have a right to know if the agency is helping American secret services find al Qaeda and Taliban targets in Pakistan, reports the Daily Express.

“The evidence is pretty compelling that we are providing that kind of information to the Americans… The British people have a right to know about the policies being pursued by their Government,” Lord Macdonald said.

“I’ve been to Pakistan and I have seen what drone strikes can do. Innocent people do get killed as a result of misplaced strikes. It is also succeeding in creating a new generation of people with huge resentment against the West, fuelling the kind of terrorism we are trying to fight. The fact this is one-sided, mechanised and robotic gives these strikes a particularly sinister dimension,” he added.

It comes after reports that a GCHQ official admitted the agency was proud of providing “locational intelligence” to the CIA.
